Fxak69 pafg 222143 afdafg northern alaska forecast discussion national weather service fairbanks ak 143 pm akdt Thu aug 22 2019 Discussion Synopsis... A front extending from northwest of kaktovik extends southwest through the brooks range and into the central interior. This will bring cloudiness and some showers to those areas through this evening, and the brooks range will likely see snow above the 2000 foot level or so. This will push east into canada overnight with another taking its place Friday night. All this is part of a broad cyclonic circulation around a low pressure area in the northern arctic. Also associated with this is a deep fetch of northerly winds, the main impacts from these being 20 to 25 kt winds along the northwest arctic and west coasts with cooler temperatures behind it, and elevated surf conditions from approximately point barrow to shishmaref this evening through Saturday. 22 12z model solutions continue to show good agreement over the larger scale into the weekend, but start to diverge toward the end of the weekend, especially in regards to how quickly the lows shortwaves rotate around the parent north arctic low, especially with the multiple shortwaves moving across the north slope. Aloft... A 521 dam low near the north pole is spinning multiple shortwaves out from its center. One shortwave extends generally southeast into the northwest territories of canada, one extends south into the eastern north slope, brooks range, and interior. Farther west, this is the system bringing a long fetch of northerly winds into the western arctic and west coasts, with a high pressure ridge currently over eastern russia. A 550 dam area of low pressure south of st lawrence extends a trough into the yk delta this afternoon. The low will shift west Friday, strengthening to a 516 dam low, with shortwaves roughly in the same areas as today. The ridge over russia will expand eastward to impact portions of the west coast, for the most part keeping precipitation out of the area, at least in the seward peninsula. Saturday, the low drops south and east, pushing the main shortwave east over far eastern interior and the yukon territory, and dropping another shortwave over the west coast. Stronger winds can be expected Friday and Saturday with the tighter pressure gradient anticipated over the north slope and western arctic coast. The low near st lawrence island will shift south to st paul island by Fri afternoon as a 548 dam low, with a trough extending through bethel and into the alaska range. This feature will continue southeast and be over the aleutians as a 552 dam low by Saturday night. Arctic coast and brooks range... a front dropping south and east will bring showers and increasing winds from point hope to utqiagvik this evening. Overnight and Friday, this front will push further southeast, with showers from nuiqsut east and more snow moving into the brooks range. As the

low pressure system moves closer to the coast, expect gusty west winds of 20 to 25 mph from deadhorse east and northwest winds of 15 to 20 mph across the higher elevations of the eastern brooks range Friday. Friday night and Saturday, the low will be not far offshore north of demarcation point, with west to southwest winds of 20 to 30 mph across the eastern portions of the north slope. Wave heights of up to 8 feet are expected off shore of kaktovik at this point, but impacts should be limited as the winds will be generally southwesterly, so waves should break away from shore. Gusty west winds return Sunday, as another shortwave makes its way across the north slope. Expect another day of cooler temperatures Friday before a warmup back to the mid to upper 40s on Saturday and Sunday. Temperatures will fall again next week, however. West coast and western interior... generally good weather is expected the next few days. Expect a few showers tonight and Friday over the seward peninsula associated with a weak shortwave, but otherwise weak ridging will keep the majority of the region dry into the weekend. The main concern will be the northerly winds increasing tonight through Saturday. Expect 20 to 30 mph winds through this period. Elevated surf is expected along north facing coastlines from point barrow west and down to shishmaref, as well as on st lawrence island. Temperatures will be a couple of degrees cooler Friday and Saturday. Central and eastern interior... expect light winds and periods of showers through the weekend and into early next week as weak surface low pressure sits over the eastern interior. With less than a quarter of an inch of rain expected over 2 to 3 days, this will not impact the rivers much at all. Temperatures will remain pretty steady through the weekend, with a slight cooling trend early next week. Coastal hazard potential days 3 and 4... None. Expect elevates seas off the arctic coast Sunday, but highest wave action is expected to remain offshore. Fire weather Have very little concerns regarding fire weather. Relative humidity values will remain near or above 40 percent across the state. Winds will be pretty light with no thunderstorm activity expected. Hydrology River levels have been falling and will continue to fall for the next few days, although ground water remains high. Some ponding in low lying areas along rivers and streams is still possible, but will be less likely as river levels continue to fall. Any additional rainfall over the next few days will not significantly affect water levels. Continue to use caution around waterways as trees and other debris will be making its way downstream.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
